Strong rip currents hit coast

San Diego County beaches will be hit by strong rip currents throughout the weekend, says the National Weather Service. A swell out of the south-southwest is producing waves in the 3' to 4' range at many beaches. The rips will be amplified by larger-than-normal high tides. There will be a 6' 9'' high tide at 8:41 p.m. Saturday, and a 6' 2'' high tide at 9:28 p.m. on Sunday. Beach-goers are encouraged to swim and surf in front of lifeguard towers that are staffed. Sea surface temperatures are currently in the 70-73 degree range.
